I thought of some master account, but didn't think of how to get that. I
will consider this, thanks!

It sounds like it is even more elegant than copying
/var/[lib,spool]/imap as it avoids rebuilding and converting stuff, correct?

Afai understand this would mean these 3 dirs:

sigh ... I don't even *know* if I use berkeley.

I suspect, yes, I see db-files in /var/lib/imap:

# ls /var/lib/imap
annotations.db
db
db.backup2
deliverdb
mailboxes.db
[...]

Is the conversion hard to do?
What do you recommend?

You talk of the sort order in the mail-clients view?

If things work out, I don't have a problem with some time spent.

addon:

I assume to use skiplist from doing this:

# grep berk /etc/cyr*
# grep skip /etc/cyr*
/etc/cyrus-imapd.conf:duplicate_db: skiplist
/etc/cyrus-imapd.conf:tlscache_db: skiplist
/etc/cyrus-popd.conf:duplicate_db: skiplist
/etc/cyrus-popd.conf:tlscache_db: skiplist
/etc/cyrus-timsieved.conf:duplicate_db: skiplist
/etc/cyrus-timsieved.conf:tlscache_db: skiplist

OK?

"file {filename}" should tell you what they are. With 2.2.x it is likely
they are Berkeley.   Berkeley is an administrator's nightmare.  If they
Berkelely convert them and make sure the server still works *BEFORE*
migrating if you are using a rsync method.

cvt_cyrusdb  [I think this was around in 2.2x?]


see page 97

You'll probably need to change the database type in imapd.conf as well.

No, it is sorting order in the database.  It is much easier to convert
everything before migrating.

ok. I rsync /var/spool/imap/user now.

Does it matter:

new server has one subdir per character:

a
b
c
d
...

while old server has:

auser1
auser2
auser5
...

?

I will give it a try in the evening when I can stop the server for a moment.

So the initial conversion on the old box takes care of the sorting
issue, do I understand correct?

It works now.

Instead of "su cyrus -c " I su-ed to cyrus ... in there it worked for
deliver.db now.

# file delnew.db
delnew.db: Apple QuickTime movie (modified)

So the other 3 dbs seem to be already skiplist, right?

# file /var/lib/imap/*.db
/var/lib/imap/annotations.db:  Apple QuickTime movie (modified)
/var/lib/imap/deliver.db:  Berkeley DB (Btree, version 9, native
byte-order)
/var/lib/imap/mailboxes.db:Apple QuickTime movie (modified)
/var/lib/imap/tls_sessions.db: Apple QuickTime movie (modified)

If these four dbs are all I have to look at, I assume I could stop
cyrus, replace deliver.db and try starting over?

Thanks so far, sorry for my detailled approach, I just want to do it
right ...

I am nearly there and it makes me happy!

cyrus 2.4.12 runs with the slightly adapted config from the older
server, it indexed all the mailboxes ... and I was already able to
contact via thunderbird and a webmailer.

That is great!

So far only sieve doesn't work yet, although something listens on port
2000 there is no timsieved process ... hmm, gotta dig further.

And:

imaps[18096]: IOERROR: opening /var/imap/user_deny.db: No such file or
directory

Important?

-

Right now old/productive and new/test server drift apart.

May I just rsync over the mailboxes changes when I want to switch?

Or should I start over with clean and fresh directories on the new server?

Thanks a lot!

Migrating this server was something stressing me a lot when thinking
about it. Now I see it will be done soon!

Thanks!

Migration from imap will grow used space because will ignore single instance

Somewhere along the line some distributions changed the SIEVE port.

Stop the new server
Rsync from the old server
Start the new server 
Make sure everything is working on new server
Stop the new server.
Stop the old server.
Rsync again.
Start the new server.

You need to perform the last rsync from a cold server. But it should be
pretty quick as it will only grab the few changed items.

Wouldn't that mean that I overwrite stuff with older files?

rsync -av   without "--delete", correct?

And I would have to convert the deliver.db once more, correct?

I will retest that later as I saw a minor issue with some index-file.
Overall it looks very promising right now.

rsync will only sync over newer files and files that have changed. I 
would use --delete as you don't want mails that have been deleted on the 
live server to remain on the new server.

I accept that just to get to the new hardware asap.
I don't have that much data so it doesn't matter that much right now.

OK, so I will skip that one.

My current problem is configuring saslauthd.

Both servers are configured to use pam_mysql (for imap/pop/smtp) and
talk successfully to the db on the new server.

IMAP works fine on both.

Also both Postfixes talk to the new db.

Only saslauthd on the new server is still pointing at the old db on the
old server.

I have

 /usr/sbin/saslauthd -a rimap -O 10.1.0.3

which works successfully.

(10.1.0.3 is the VPN-IP of the old box, .4 the new one)

While

/usr/sbin/saslauthd -a rimap -O 10.1.0.4

or

/usr/sbin/saslauthd -a rimap -O 127.0.0.1

or

/usr/sbin/saslauthd -a pam (-r)

don't work.

Any new behavior in the newer cyrus-sasl?


# smtpd.conf

mech_list: PLAIN LOGIN
pwcheck_method: saslauthd

same as on the old box ... hmm.
cyrus-imapd.conf was also copied and contains:

sasl_pwcheck_method: saslauthd
sasl_mech_list: plain login
sasl_log_level: 1

exactly the same pw works when I point saslauthd against the old
imap-server.

Is some encryption my problem?

pam_mysql package on new server has (gentoo-style) USEflags "openssl
sasl ssl"  sounds promising ...


Now this is the last single thing needing the old DB ...

squatter stops working as it hits an index of a user with a trailing
space in its name.

seems like a typo ...

within web-cyradm I don't see that user.

Should I remove it with cyradm? May I simply delete its files/indexes?

Stop the old server. Rsync again. Start the new server.

You need to perform the last rsync from a cold server. But it should
be pretty quick as it will only grab the few changed items.

Wouldn't that mean that I overwrite stuff with older files?

rsync will only sync over newer files and files that have changed. I
would use --delete as you don't want mails that have been deleted on
the live server to remain on the new server.

rsync -av without "--delete", correct?

And I would have to convert the deliver.db once more, correct?

Or just ignore it and let Cyrus create a new one when it starts.

I will retest that later as I saw a minor issue with some index-file.
Overall it looks very promising right now.

Thanks to all of you for your support (so far) ;-)

I saw no problems yesterday with only copying stuff over.

But cleaning up things and somehow regenerating structures might be good
at this point, yes.

Sigh, another thing:

I can't connect to cyrus via cyradm:


$ cyradm --user cyrus localhost
verify error:num=19:self signed certificate in certificate chain
IMAP Password:
  Login failed: authentication failure at
/usr/lib64/perl5/vendor_perl/5.12.4/x86_64-linux/Cyrus/IMAP/Admin.pm
line 120
cyradm: cannot authenticate to server with  as cyrus

I assume it might have to do with saslauthd?

I don't want to try around right now as stuff authenticates OK against it.

Why does it ask "IMAP Password" ? It should read from sasldb, correct?

Please advise, thank you.

No, there is a split.  On CentOS6 [at least] /usr/sbin/saslauthd [the
*service*] is provided as part of the cyrus-sasl package.  The SASL
plugin/library needed to *other services* to *USE* authentication via
saslauthd is provided by the cyrus-sasl-plain package.  Installing one
does not, by dependency, install the other.

I assume it has to do with the pam-file. It should somehow read sasldb

I am not sure which way to go with all this sasldb/saslauthd stuff.

For SMTP-Auth things work, it reads mysql-entries via saslauthd right now:

# cat /etc/sasl2/smtpd.conf
mech_list: PLAIN LOGIN
pwcheck_method: saslauthd
log_level: 3

and saslauthd uses pam and pam for imap uses pam_mysql only ...

Will dig further this evening if I have to add lines to the pam-file.

Afai understand I only need sasldb for managing cyrus via cyradm?

Would it be possible to use my IMAP-user (from the mysql-query via
pam_mysql) for cyradm-work?

oh slowly slowly

After setting a UNIX-pw for (admin-user) cyrus, I am able to use cyradm
from the shell.

But: web-cyradm does not open/use cyradm somehow.
Stuff is created in the DB, but there are no mailboxes created.

The conf.php looks fine but there is no login to cyradm logged at all.

Any ideas someone?

I am near to switching servers now, and I just tested the instructions
mentioned there.

The procedure even helped to skip the mentioned mailbox with the

Everything is indexed now ... looking forward to actually move over soon.

The mentioned howto

http://cynici.wordpress.com/2010/12/06/how-to-migrate-32-bit-cyrus-imapd-mailboxes-to-64-bit/

uses "-aP" ...   so you recommend "-aPH" ?

I don't care much about disk usage, and my tests didn't show significant

Yes. With single instance store if 10 people receive the same e-mail it 
is only stored once on the filesystem and the other 9 are hardlinked to 
the file.

Yes, singeinstancestore uses hard links to keep a copy of the same
message in multiple mailboxes.

ah, ok  so I should start over syncing completely?
Or does adding "-H" to my commands and re-running also do the trick?

Thanks, Stefan

ok, did that-

I am UP and running on the new system.

Only issue: the SEEN-flags didn't quite come over correctly, at least
for my accounts  (does it correspond w/ the client?).

I assume my users will have to live with it. period.
System is up and users access mailboxes already, so ...

Could I somehow get rid of these lines in /var/log/messages :

fetching user_deny.db entry .

Reduce log level?

Thank you all for your support!

Stefan
